Abstract

A method for forming an access passage for a gas turbine engine of an aircraft propulsion system includes installing a tooling jig on an engine case of the gas turbine engine at a port at a turbine section radially outward of a turbine vane stage, aligning the tooling jig on the engine case and fixedly mounting the tooling jig on the engine case, and drilling a first access aperture of the access passage through the inner ring along the tooling axis with a drill bit inserted into the first turbine vane through a tooling aperture of the tooling jig. The access passage extends through the turbine vane stage to a rotor cavity disposed radially inward of the turbine vane stage and between an upstream rotor stage and a downstream rotor stage of a bladed turbine rotor.
